Description

A COMPOSITION COMPRISING AN EXTRACT OF COMBINED HERBS CONSISTING OF ACANTHOPANAX KOREANUM NAKAI AND CRINUM ASIATICUM VAR. JAPONICUM SHOWING PREVENTING ACTIVITY OF BALDNESS AND STIMULATING ACTIVITY OF HAIR GROWTH

The present invention relates to a composition comprising an extract of combined herbs consisting of Acanthopanax koreanum Nakai and Crinum asiaticum var. japonicum showing preventing activity of baldness and stimulating activity of hair growth.

Hair follicle, a very complex organ, consists of an inner root sheath (IRS), outer root sheath (ORS), hair shaft, hair matrix cell (Paus et al., J. Invest. Dermatol., 113, pp523-532, 1999), and dermal papilla cell, which plays an important role in hair growth among various kinds of the cells forming the hair follicle (Ferraris et al., Exp. Cell Res., 10, pp37-46, 1997).

Hair follicle develops through the interaction between the mesenchymal cell and epithelial cell during an embryogenesis. Normal hair growth consists of repeated three phases, i.e., anagen, catagen and telogen stages (Paus et al., N. Engl. J. Med., 341, pp491-497, 1999). Especially, human hair has the longer growth period than any other animal hair or the other part hairs of the human body (anagen, 2-5 years; catagen, several days-several weeks; telogen, three months). During the anagen stage, the cell consisting of hair follicle including the keratinocytic cell of matrix surrounding the dermal papilla, proliferates and grows hair. During the catagen stage, within the hair follicle, apoptosis, condensation of the dermal papilla, and the reconstitution of extracellular matrix serially occur (Paus et al., J. Invest. Dermatol., 113, pp523-532, 1999) to stop the cell division and slow the hair growth. The hair follicle at telogen stage falls out except the permanently lasting parts comprising the bulge region of hair follicle at the state of quiescence of growth to restart new anagen (Hardy MH., Trends Genet., 8, pp55-61, 1992).

Several drugs promoting hair growth approved by the Food and Drug Administration (FDA) have been developed, for example, ‘Minoxidil’ (Buhl et al., J. Invest. Dermatol., 92(3), pp315-320, 1989) and ‘Finasteride’ (Van Neste et al., Br. J.Dermatol., 143(4), pp804-810, 2000).

As an alternative approach, there have been attempts to develop new therapy using herb extract having hair growth stimulating effect: for example, an extract of Crinum asiaticum Linne var. japonicum Baker or the lycorine compound isolated therefrom disclosed in Korea Patent Registration No, 10-0979269; an extract of Acanthopanax koreanum Nakai disclosed in Korea Patent Registration Nos, 10-1151587 & 10-1151555, etc.

However, there have been still needed to develop new drugs or substances showing more potent activity without adverse action till now.

Crinum asiaticum Linne var. japonicum Baker belonged to Amaryllidaceae is distributed to Korea, tropical asia, Japan, North America. It has been reported to comprise various ingredients, for example, phenanthridine alkaloids, triterpene alcohols, and flavonoid (Min BS, et al., Cytotoxic alkaloids and a flavan from the bulbs of Crinum asiaticum var. japonicum. Chem Pharm Bull (Tokyo). 49(9):1217-1219, 2001) and to show various medicinal effect, for example, anti-viral activity of various alkaloids (Gabrielsen B, et al., Antiviral(RNA) activity of selected Amaryllidaceae isoquinoline constituents and synthesis of related substances. J Nat Prod. 55(11):1569-1581, 1992), anti-malarial activity (Likhitwitayawuid K, et al., Cytotoxic and antimalarial alkaloids from the bulbs of Crinum amabile. J Nat Prod. 56(8):1331-1338, 1993), cyto-toxicity activity (Abdel-Halim OB, et al., New crinine-type alkaloids with inhibitory effect on induction of inducible nitric oxide synthase from Crinum yemense. J Nat Prod. 67(7):1119-1124, 2004), etc.

Acanthopanax koreanum Nakai belonged to Araliaceae is distributed to only Cheju island in Korea. It has been reported to comprise various ingredients, for example, syringaresinol diglycoside (Kim YH, et al., Studies on the constituents of Acanthopanax koreanum Nakai(1)., Kor. J. Pharmacogn, 16, pp.151-154, 1985), acanthoside D, syringoside (Hahn DR, et al., A study on the chemical constituents of Acanthopanax koreanum and its pharmacobiological activities., Yakhak Hoeji, 29, pp.357-361, 1985), eleutheroside B and E (Chung BS, et al., Studies on the constituents of Acanthopanax koreanum Nakai., Kor. J. Pharmacogn, 17, pp.62-66, 1986), falcarindol, methyl n-hexacosanoate, and coniferin (Kim YH, et al., Studies on the chemical constituents of Acanthopanax koreanum, Arch. Pharm. Res, 11, pp.159-162, 1988), pimaradine diterpene (Kim YH, et al., Pimaradine diterpenes from Acanthopanax koreanum. J. Nat. Prod, 51, pp.1080-1082, 1988), sumogaside (Kim YH, et al., Diterpene glycoside form Acanthopanax

koreanum., Kor. J. Pharmacogn, 21, pp.49-51, 1990), lupane glycosides (Choi HS, et al., Lupane glycosides from the leaves of Acanthopanax koreanum., Chem. Pharm. Bull, 56, pp.1613-1616), etc and to show anti-rheumatic activity, ant-diabetic activity, hepato-protective activity etc (Perry LM, et al., Medicinal Plants of East and Southeast Asia. MIT Press, Cambrige, p.41, 1980).
